Signs Your Circuit Breaker Is Failing – Warning Signs & Solutions

Identifying a failing circuit breaker early can prevent equipment damage, fires, or system downtime. Here are the most common warning signs and corrective actions.

1. Breaker Won’t Reset

If it trips and refuses to reset, internal contacts may be welded or corrosion may be present.

2. Frequent Tripping

Repeated trips even under normal load suggest degradation or miscalibration—testing and adjustment are needed.

3. Burning Smell or Noise

A burnt odor or buzzing can indicate arcing—cut power and inspect immediately.

4. Warm or Hot Breaker Panel

High impedance or loose connections cause heating—use infrared tools to locate hotspots.

5. Age & Wear

Older breakers may degrade—replace after ~15–20 years or after major events like lightning strikes or overloads.

Next Steps

Hire a licensed electrician to test, repair, or replace the breaker. Don’t ignore early warning signs.
